Libei Bei Jing Ze did this because he was a patient with hyperthyroidism. Beibei, formerly known as Li Jingze, was born in Beijing and Lanzhou, 1995. The experience is from YY network players to offline champions. Beibei's earliest experience was rap battle on YY, and the live broadcast room was often full. Later, Beibei was suspected of cutting off his little finger in the live broadcast. He always said that he had a clear conscience. The related platform has processed Beibei's account, permanently banned broadcasting, and related illegal videos have been offline. Beibei's staff responded that Beibei himself was a hyperthyroidism patient and was wronged by cyber violence. He wanted to seek justice and prove that he had a clear conscience before making such an extreme proof.
